Control means for copy sheet feeding and moistening means in address printing machines

Claim 1

In a machine for spirit transfer printing of a moistened area of a copy sheet by a master card which is superposed on the moistened area during printing; the combination of a copy-sheetreceiving station, a printing station, a rotatable drive shaft, means for indexing rotation of said drive shaft at one revolution intervals, feed rollers driven by said drive shaft for passing a copy sheet from the receiving station through the printing station during one revolution of the drive shaft, a rotatable countershaft, moistening means mounted on said countershaft and actuated thereby for moistening a selected area of a copy sheet during its passage from the receiving station to the printing station, further means on said countershaft and conjointly actuated thereby for superposing a master card on the selected area of the sheet following moistening the and during passage of said sheet from the receiving station to the printing station, retractable positive stop means for holding a sheet at the receiving station, means actuated by said drive shaft for retracting said stop means when rotation of the drive shaft is initiated and for projecting the stop means when one revolution of the drive shaft is completed, and an adjustable drive mechanism between said drive shaft and said countershaft whereby actuation of said moistening means and of said card superposing mean may be preadjusted relative to retraction of said stop means and resultant feeding of a copy sheet from the receiving station to the printing station so that sheet moistening and superposition of a master card occur at an adjustably selected area of the sheet.
